Improving fridge efficiency

A recent client has a number of fridges, including wine fridges. Other work had reduced the pool energy (see pie chart) to a reasonable level; the fridges (“power”) were next on the list.

By writing some custom queries and graphics, the client could plug each fridges into a spare circuit and deduce the annual cost per fridge.

The dashboard shows both the energy and money cost.

And the results are:

  • Wine fridge 1 (near window) – $73/year 290 kWh/y
  • Wine fridge 2 () $90/year 359 kWh/y
